Code to solve the Advent of Code puzzles. This year, I'm trying to use the puzzles as a prompt to learn Haskell.
Learn you a Haskell, Introduction to Haskell 98, and Hackage are good resources.
I'm using the basic Haskell Platform installation, togeher with Stack
to manage the packages and dependencies (install with
$ sudo aptitude install haskell-platform haskell-stack
).
I have one package for each day, to save time waiting for Stack to check every executable before compiling what's changed. Each package needs a separate directory tree and a separate .cabal
file.
To work on a project, cd
into that project's directory.
Compile with
stack build
or
stack build adventofcode1601
Run with
stack exec advent01
Run interactively with
stack ghci adventofcode1601:exe:advent01
To profile, use
stack build --executable-profiling --library-profiling --ghc-options="-fprof-auto -rtsopts" adventofcode1601
then run with
stack exec -- advent01 +RTS -p -hy
Build this readme file wth
pandoc -s README.md > README.html
I'm also using some extra libraries. Before installing, run cabal update
then set library-profiling: True
in ~/.cabal/config
. Then install the packages with
$ cabal install MissingH
$ cabal install parsec-numbers
$ cabal install cryptonite
$ cabal install pqueue
Compile the code with
ghc --make advent01.hs
then run it as
advent01
If you're profiling, compile and run with
ghc -O2 --make advent01.hs -prof -auto-all -caf-all -fforce-recomp -rstopts
time ./advent01 +RTS -p -hy
and create the profile picture with h2ps advent01.hp
.
(Using the Modest style.)
